Description
Overview
GAOTek Laser Methane Gas Leak Detector instrument consists of optical and mechanical system, signal processing system, display and alarm system and shell components. It is mainly used to measure the concentration of methane or methane-containing gasses (natural gas, gas or similar gasses) over a long distance, and can be widely used for rapid positioning and detection of gas pipelines.
It handheld laser methane telemetry instrument emits an infrared laser to the detection point, which can quickly measure the concentration of air mass between the detection point and the telemeter. In order to observe conveniently, the telemeter also emits a visible red laser to the detection point at the same time. The detector can detect the methane concentration value of the detected location in real time and accurately, display and store it, and give an sound and light alarm when the alarm value exceeds, so that the personnel can make follow-up disposals.
Features
- Miniaturized design, easy to carry, service life up to 10 years
- Fast response at millisecond level, greatly reduce inspection time
- PPM class high sensitivity
- Gas leakage caused by early loosening of screw can also be detected in time
- Non-contact detection, especially suitable for areas where personnel are difficult to access or higher position from the ground
- Can be tested through glass to ensure the personnel safety
- Fingerprint characteristics, only response to the detected gas
- Can not interfered by other gasses
- Not poisoning, drifting, greatly increase the product service life
